MAY 26, 1993

Lege Artis Medicinae - 1993;3(05)

[Among the epidemic diseases that have terrified and frightened mankind for centuries, the plague, also known as the "black death", is the most common. Even today, many of us shudder at the mere mention of its name, although fortunately we have little personal experience of the disease. What was the constant experience of successive generations in the Middle Ages is almost unimaginable to 20th century man: an epidemic that regularly appeared and claimed huge victims. In the old chronicles, we often find descriptions of plague epidemics which, although they tend to exaggerate the number of victims, give a vivid picture of the shock of the devastating power of the disease in the minds of the people of the time. ]

[The prerequisite of T cell recognition: antigen processing and presentation]

RAJNAVÖLGYI Éva

[Multiple regulatory mechnanisms are activated wit hin the immune system to maintain the homeostasis of the organism. A key element of these processes is the specific recognition of antigens mediated by T and B lymphocytes. This is the basis of clonal selection and antigen specific activation of the immune system (LAM 1991. 1(18):1308–1314.) which results in the most efficient elimination of the antigen. T cells play a predominant role in the discrimination of self and non-self structures. Antigen specific activation of T cells results in the expression of cell surface molecules and in the production of different lymphokines of high biological activity, which define the possibilities for cell to cell interactions and influence the function of different cell types affecting the outcome of the immune response. The appropriate activity of functionally distinct T cells enables the most efficient mobilization of effector mechanisms leading to the elimination of the antigen without destroying self components. In order to exert their regulatory and effector functions they require a well regulated collaboration with antigen presenting cells. This review summarizes our present knowledge on the intracellular degradation and transportation pathways occuring on in antigen presenting cells determining the antigen specific functions of T cells. It is well established that these events influence the efficacy or protection against pathogens and have a basic influence on the normal or pathological outcome of autoimmunity.]

[Thoughts on radical hysterectomy]

BŐSZE Péter

[Radical hysterectomy and pelvic lymphade nectomy have been used for the treatment of carcinoma of the uterine cervix in most Western countries for decades. These surgical procedures, however, have rarely been advocated in Hungary. Advantages and disadvantages of radical hysterectomy with pelvic and paraaortic lymph node dissection are discussed. Emphasis is placed on patient selection. It is the author's view that radical surgery does have a place in the management of cervical cancer. The patient should be informed about the possible treatment modalities available such as radical surgery, radical radiation therapy or a combination of surgery and irradiation, and she should be involved in the decision making process. Radical hysterectomy with pelvic lympha denectomy is a major operation with potentially significant intraoperative and postoperative complications. A dequate surgical skill and sufficient experience are required and this procedure should be regularly practiced. For these reasons, it is probably best performed in cancer centres.]

[The role of computed tomography in tumor staging of bronchogenic carcinoma]

HEILER Zoltán, PÁLFFY Gyula, KOSTIC Szilárd, MONOSTORI Zsuzsanna, REPA Imre

[Operability of lung cancer is based on the size and local extension of the tumor as well as the presence of lymph node and distant metastases. Agreement and disagreement between CT and surgical tumor staging was investigated for 197 cancer patients after surgery. Sensitivity and specificity of CT prediction ranged 57–93% and 71–100% ac cording to tumor stadium. CT diagnosis has been relatively unreliable in describing tumor propagation along the pulmonary veins (less frequently arteries) towards the atrium and in recognizing a discrete tumor invasion of the mediastinum. Local thickening of the parietal pericardium, and small pericardial effusion have been considered as indirect signs of pericardial tumor infiltration. MR examination have been found to be a supplemental technique for assessing tumor spread to the great vessels of the mediastinum. The authors believe on the results that new techniques, such as MR angiography and indirect CT signs will help in making a more accurate preoperative diagnosis of lung cancer.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

[Vaccines against COVID-19 pandemic]

FALUS András, SZEKANECZ Zoltán

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

A variant of Guillain-Barre syndrome after SARS-CoV-2 vaccination: AMSAN

TUTAR Kaya Nurhan, EYIGÜRBÜZ Tuğba, YILDIRIM Zerrin, KALE Nilufer

Introduction - Coronavirus disease 2019 (COVID-19) is a respiratory infection that has rapidly become a global pandemic and vaccines against SARS-CoV-2 have been developed with great success. In this article, we would like to present a patient who developed Guillain-Barré syndrome (GBS), which is a serious complication after receiving the inactive SARS-CoV-2 vaccine (CoronaVac). Case report – A 76-year-old male patient presented to the emergency department with nine days of progressive limb weakness. Two weeks prior to admission, he received the second dose of CoronaVac vaccine. Motor examination revealed decreased extremity strength with 3/5 in the lower extremities versus 4/5 in the upper extremities. Deep tendon reflexes were absent in all four extremities. Nerve conduction studies showed predominantly reduced amplitude in both motor and sensory nerves, consistent with AMSAN (acute motor and sensory axonal neuropathy). Conclusion - Clinicians should be aware of the neuro­logical complications or other side effects associated with COVID-19 vaccination so that early treatment can be an option.

Acute transverse myelitis after inactivated COVID-19 vaccine

ERDEM Şimşek Nazan, DEMIRCI Seden, ÖZEL Tuğba , MAMADOVA Khalida, KARAALI Kamil , ÇELIK Tuğba Havva , USLU Ilgen Ferda, ÖZKAYNAK Sibel Sehür

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.
